"The universe is transformation; our life is what our thoughts make it." (Stoicism, Marcus Aurelius, Meditations 4:3)
True, false, good, bad, useful, not so useful, etc.? Discuss.
My thoughts:
Well, yeah. Everything is always changing, including our place in that everything.
And one's place? Well, as The Dude said, "that's just like, your opinion, man."
I've known people who are incredibly cheerful under circumstances I'd consider dire, and people who seem to have it all but live in a constant state of depression.
Are our situations all in our own minds? Of course not. But ultimately we define what those situations mean to us. The people in the cheap seats get to have opinions too, but each of us is both the director and the star -- and the most important critic -- of his or her own performance.
